The individual who opened fire at an unmarked ICE van in Dallas on Wednesday had researched online for applications tracking the movements of ICE agents and left a note expressing hope that his attack would instill “real terror” in them, according to FBI Director Kash Patel. The suspect, 29-year-old Joshua Jahn, killed an illegal alien detainee and injured two others before fatally shooting himself. Police recovered unspent bullet casings marked with the phrase “anti-ICE” at the scene. While ICE was clearly the target, no agents were harmed in the attack.

Patel shared details of the investigation on X Thursday, describing the incident as a planned left-wing domestic terror act. Evidence included handwritten notes found at the scene, such as one stating, “Hopefully this will give ICE agents real terror, to think, ‘is there a sniper with AP [armor piercing] rounds on that roof?’” The suspect had downloaded a document listing DHS facilities, searched for ballistics information and a video titled “Charlie Kirk Shot Video,” and explored apps tracking ICE agent presence between August 19 and September 24.

SignalSafe, an app monitoring ICE activity nationwide since April, was also cited as part of the investigation. FBI field agent Joe Rothrock in Dallas linked the attack to broader “targeted violence” against ICE agents tied to President Trump’s immigration policies. Recent incidents include a Chicago suburb where an ICE officer was severely injured after being dragged by a fleeing vehicle, a Yakima, Washington, fire at an ICE office, and a July 15 incident in Dallas where an ICE agent was dragged behind a vehicle.

Other attacks cited include a July 7 shooting at a Border Patrol annex in McAllen, Texas, which left two officers and one employee injured, and a July 4 ambush by antifa agitators in Alvarado, Texas, involving fireworks and gunfire. A June 18 protest in Portland, Oregon, saw federal agents deployed to manage an anti-ICE uprising.

The Department of Homeland Security reported a 1000% surge in violence against ICE personnel, attributing it to “hateful anti-ICE rhetoric.” DHS criticized “sanctuary politicians” for endangering agents, stating, “Hateful anti-ICE rhetoric costs lives.” Federal authorities also arrested six masked individuals in Eugene, Oregon, following an anti-ICE demonstration.
